Sustainable Options Promise to Redefine the Electricity Supply of Roraima

On October 25, during a special meeting of the Electric Sector Monitoring Committee (CMSE), the National Electric System Operator (ONS) outlined crucial recommendations to facilitate the import of electricity from Venezuela to Brazil. This action aims to replace the reliance on costly thermal power plants that supply the system in Boa Vista, the capital of Roraima. The main energy supplier for this initiative will be the Guri hydroelectric plant, located in Venezuela.

The Importance of Reliable Data

For informed decision-making, the ONS expressed the need for detailed and up-to-date data on the Venezuelan Electric System. This step is essential to ensure the integrity of the joint operation between the two countries, especially as the interconnection intensifies. It is worth noting that the information currently held by the ONS is based on the last occasion when Roraima was connected to the Venezuelan electricity grid.

During the meeting with the CMSE, the ONS shed light on the pros and cons of two reliability criteria discussed to re-establish this connection with the Venezuelan electric system. The criteria examined include operating under the N-1 guideline, without power interruption in Roraima, and operation with controlled load shedding (with the activation of ERAC). The crucial point raised to ensure safety in the exchange of energy is the ability of the connection to operate continuously. This means that the amount of imported energy must adjust according to demand, reaching near-zero values during periods of lower consumption in Roraima if necessary.

Prevention and Safety First

To ensure a stable interconnected operation, the ONS emphasizes the imperative of implementing a Special Protection System (SEP). This mechanism would serve to disconnect the interconnection in adverse situations occurring in the Venezuelan system, thus protecting both Roraima and Venezuela from potential disturbances in the electric flow.

This move, promoted by the ONS, not only aims to optimize the costs associated with electricity supply in Roraima but also seeks to strengthen bilateral energy relations, ensuring a more sustainable and interconnected future for both nations.

ONS Strategies for Importing Venezuelan Energy to Roraima

Sustainable Options Promise to Redefine the Electricity Supply of Roraima

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

Brazil filled the Northeast with wind turbines but now faces the side effect of 705 giant blades reaching the end of their lifespan by 2032 just in Rio Grande do Norte, while the world projects 43 million tons of waste by 2050.

India approved the country’s first submerged road-rail tunnel, 15.8 kilometers dug under the bed of the Brahmaputra River.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

10 giant tortoises are reintroduced and, in just 6 months, trigger changes that lead scientists to investigate a phenomenon absent for 180 years; the numbers recorded on the island impress researchers from around the world.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

What many people consider a weed has become a bicycle in the hands of a Chilean. José Tomás transforms coligüe, a native bamboo that grows up to five times faster than pine, into bikes, canes, and cutlery.

Only 28% of the ocean floor has been accurately mapped, less than what is already known about the surface of Mars and the Moon, and scientists consider the topic strategic for Brazil, with a global goal to map everything by 2030.

Japan wants to bury a 500 km “cargo conveyor” between Tokyo and Osaka to replace up to 25,000 trucks per day, move goods through tunnels and automated driverless corridors, and avoid a logistical collapse in an increasingly aging country.

GAC launches “Chinese hybrid Kombi” with 7 seats cheaper than Tiggo 8 Pro Plug-in Hybrid in Brazil; for around R$ 177,000 in conversion without taxes, the Trumpchi E8 PHEV has a 2.0 engine, DHT transmission, an electric range of 150 km, and a premium family cabin for those living in China.

The world has bet on green hydrogen as the fuel of the future, but now faces the side effect: producing 1 kilogram requires about 9 liters of ultrapure water, and the largest projects on the planet are precisely in the driest regions of the Earth, where water is already scarce for people.

Africa has about 500,000 cell towers and most still burn diesel to operate, while companies rush to cover antennas with solar energy and avoid signal blackouts.

Farmers swapped diesel for solar panels in Pakistan, powered irrigation pumps almost cost-free, expanded rice fields, and now groundwater has become a red alert in the countryside.

Migrant workers left the world’s largest renewable energy park in India after extreme heat, 12-hour shifts, delayed wages, and poor accommodations at a site that still promises to supply 18 million homes.

Taiwanese fishermen accepted offshore wind turbines in the name of clean energy, but now they say that old routes have disappeared, fish have decreased, and income has become uncertain on the coast.
